Test results:
Interpretation
Charging system is normal, the output
voltage of engine is 13.5V 14.7V.
~
Charging system is under-voltage,
the voltage is lower than 13.5V.
The voltage of charging system is higher
than that of vehicle voltage stabilizer.
Generator voltage output is not detected.
Check if the connector and generator belt is normal.
Test via current waveform, for example, the diode is
damaged due to high ripple voltage of diode.
Decision
Charging voltage is normal.
Charging voltage is low.
Charging voltage is high.
No voltage output.
